2.)  Heavy rains will cause localized flooding: The overlying atmosphere Tuesday evening remains moisture laden from the recent heavy rains over the last several days. As the low pressure system gets into closer range now, along with its cold front, which has moved ashore on Kauai, we’ll begin to see increasing showers. We’re moving into a prolonged period of off and on showers, much of it will likely be in the form of rain. This rain will be falling on soil that is already saturated, which strongly suggests that there will be lots of runoff. This runoff is what causes flooding, and I would say that flooding is likely under these circumstances. Everyone here in the islands should be very aware that there will be poor visibilities in heavy rain at times, and that driving on flooded roads is very dangerous. The chance of flash flooding exists, especially if thunderstorms break out here and there. A flood watch is now in effect across all of the state of Hawaii through Thursday afternoon.

3.) Rough ocean conditions: All of the strong winds coming into the state, will be blowing on the ocean surface, which in turn will generate increasingly large surf. The south and west facing beaches, not accustom to large surf during the month of December, will see rising surf over the next several days. This surf will be rough and potentially dangerous, with strong currents and even undertows. This gnarly mix of breaking waves will remain quite potent, once it starts, through most of the work week. As the winds start to calm down some by the weekend, the surf will finally back off as well. Meanwhile, the north shores will continue to see larger than normal surf breaking as well, caused by storms further off into the ocean in the mid-latitudes of the Pacific. A new NNW swell will arrive late Wednesday or by early Thursday morning, making for extremely rough conditions along our north facing beaches.

It’s Tuesday evening here in the islands, as I begin writing this last paragraph of today’s narrative. Tuesday turned out to be quite a nice day in many parts of the state, albeit very much on the windy side! The Big Island saw some locally heavy showers arrive, which triggered a flood advisory for a time, but was then later cancelled. The cold front itself, at around 530pm was just arriving on Kauai’s doorstep. Heavy rains will start falling over the Garden Isle shortly, then move on to Oahu during the night…arriving over the islands of Maui County by Wednesday morning. This is going to be serious rainfall, the kind that can lead to flooding very quickly. Please use this looping satellite image so you can witness the frontal cloud moving down through the islands overnight into Wednesday. Here’s a looping radar image, so you can keep abreast of where the heaviest rains are falling too. ~~~  I will keep a close eye on this situation, and if it gets really wild, I will come back online during the night with more information. The bottom line here is be very careful when you leave the house! I hope you have a great Tuesday night wherever you happen to be spending it! Aloha for now…Glenn.

The Kona low’s cold front will move into the state on these Kona winds, bringing back heavy rains into our area later Tuesday into Wednesday. As you know, our area is already quite wet from the previous rainstorm. As the rains from this next system begin falling, we’re apt to find rain heavy enough…that flooding may become a second problem. Kona storms are infamous for bringing flood conditions at times, and this could very well be one of those occasions. The cold air aloft, associated with the Kona low, may add thunderstorms to the mix, which will add to this potential threat of flooding. This inclement weather situation bears close monitoring, with relief not in our sights until late this coming weekend, or early next week.

It’s Monday evening here in the islands, as I begin writing this last paragraph of today’s narrative. Two back-to-back Kona low pressure systems pounding our area is not common. Although, this is the time of year when we see these big rainfall producers doing their thing. If you didn’t have time or the inclination to read the weather related paragraphs above, here’s succinct version: more wet and very windy weather is on the horizon just up ahead. ~~~ Much of the state will find a slight respite from the wet weather Tuesday, although it will remain quite cloudy, with still some showers falling here and there…and getting windier as we move through the day. Please use this looping satellite image so you can see the frontal cloud band over the islands, with the next cold front in line already showing up to our NW. Here’s a looping radar image, so you can keep abreast of where the heaviest rains are falling. ~~~ I’ll be back very early Tuesday morning with a new weather narrative, describing this next unfolding wet weather event. I hope you have a great Monday night wherever you happen to be today! Aloha for now…Glenn.

An active Pacific cold front has passed across Kauai, and will arrive over Oahu Sunday evening, then slide down over the islands of Maui County early Monday. This front will continue down through the island chain, where it’s expected to stall somewhere around Maui, or perhaps as far as the northern half of the Big Island. Most areas of the state, particularly the leeward sides, saw pre-frontal showers during the day. A more generous and widespread rain even will occur as the frontal band itself moves through. If the cloud band stops over Maui County as expected, there could be quite an accumulation of precipitation there. The Big Island may remain dry, although showers may finally arrive there later Sunday into the night…along with the gusty winds ahead of the cold front. 

We can look for an upper level Kona low pressure system to form to the west or NW of Hawaii by Tuesday. This would put us on the wet side of this weather feature, with the chance that we would see copious rainfall. This is after several days of wet weather, which means that our soil will be saturated by in places then, and the prospect of flooding could become a serious matter starting Wednesday. The cold air aloft associated with this low pressure system will likely trigger locally heavy rain, with the chance of thunderstorms as well. This wet weather would likely stick around through Thursday or Friday…with improved weather by next weekend.

It’s Sunday evening here in the islands, as I begin writing this last paragraph of today’s narrative. We saw a fairly widespread rain event Sunday as a weakening cold front swept down through most of the Aloha state. There could still be be some localized flooding as the front moves through the state, with wind advisories going up before the cold front arrives as well…which are already established atop the Haleakala Crater on Maui. Here’s a looping satellite image so you can track the cold front as it moves southward towards Maui. ~~~ Here’s a looping radar image, so you can keep abreast of where the heaviest rains are falling. I would suggest that we batten down the hatches, as it will be a locally blustery and rather wet night in most areas. ~~~ I’ll be back very early Monday morning with more weather updates, I hope you have a great Sunday night wherever you happen to be! Aloha for now…Glenn. 

The latest weather maps and satellite imagery shows a stalled cold front just to the northwest of Kauai Saturday evening. This frontal cloud band is close enough to both Kauai and Oahu, that those northern islands will see the most showers falling. The rest of the state will see less showers, although there will be showers here and there along the leeward slopes…as there’s quite a bit of moisture in our overlying atmosphere. Winds will be mostly light to moderate from the south to SW direction, although gradually getting stronger as we move into Sunday. 

A more vigorous cold front will arrive Sunday across Kauai and Oahu, then slide down over the islands of Maui County during the night. This second front will progress down through the island chain, where it’s expected to stall somewhere around Maui, or perhaps as far as the northern half of the Big Island. Most areas of the state will see some of this rainy weather, and if the frontal cloud band stops over Maui County as expected, there could be quite an accumulation of the wet stuff there. The long range forecast shows another area of low pressure arriving Tuesday into Wednesday, which could drop another soaking rain then.

The models continue to show a wetter than normal second half of the new week ahead. We are now seeing a general concensus of the models describing a wet weather picture for pretty much the entire work week as a matter of fact. It appears that an upper level Kona low pressure system may form to the west or NW of Hawaii. This would put us on the wet side of this weather feature, with the chance that we would see copious rainfall. This is after several days of wet weather, which means that our soil will be saturated by then, and the prospect of flooding could become a serious matter. We need to keep an eye on this situation, and see if the models stick to their guns, or drift back to a drier outlook as they had just yesterday. 

It’s Saturday evening here in the islands, as I begin writing this last paragraph of today’s narrative. We’re moving through a weekend which will show increasingly strong winds, followed by a fairly widespread rain event later Sunday into Monday. There could be some localized flooding when the front moves through the state, and perhaps wind advisories going up before the cold front arrives as well. Here’s a looping satellite image so you can track the approaching cold front to our NW. ~~~ On another note, everyone should be very careful when going near the ocean on the north shores this weekend. A very large NW swell will be pounding those north facing beaches, making for dangerous conditions. We don’t want to see any fishermen, or anybody for that matter, being swept into the ocean! Please be careful, as the waves will be powerful, with strong currents and undertows. ~~~ I went to see a new film last evening, called Beowulf…"In the age of heroes comes the mightiest warrior of them all, Beowulf. After destroying the overpowering demon Grendel, he incurs the undying wrath of the beast’s ruthlessly seductive mother, who will use any means possible to ensure revenge. The ensuing epic battle resonates throughout the ages, immortalizing the name of Beowulf." The Boston Globe says, "the movie is hugely provocative fun." Here’s what the critics are saying about this film starring Anthony Hopkins, Robin Wright Penn, John Malkovich…and of course Angelina Jolie…among others. I enjoyed this film, although it wasn’t fabulous, I would give it a B- grade, although I could probably push it up into the B category now that I think of some of the more outrageous parts of that film! ~~~  It’s just before sunset here in Kula, Maui as I write these words. It’s breezy, with low clouds, and misty areas moving through at times. My wind chimes are sounding off, although the winds aren’t nearly as strong as I anticipate them being Sunday. I’ll be back early Sunday morning with the next updates on this unfolding wet weather situation. I hope you have a great Saturday night wherever you happen to be spending it!  Aloha for now…Glenn.
